The crystal is of monoclinic system, space group C2/c with a = 1.07388（8）, b = 2.4300（2）, c = 1.86708（14） nm, β= 104.3830（10）°, V= 4.719.4（7） nm3, Dc = 1.503 g/cm3, Z = 2, F（000） = 2196, GOOF = 1.053, the final R = 0.0343 and wR = 0.0883. The crystal structure shows that two neighboring cobalt（II） ions are linked by the bridging coordination of two a-furacrylic acid anions and one water molecule, and their end positions are respectively coordinated with two 1,10-phenanthroline molecules and two a-furacrylic acid anions, forming a dinuclear structure. Both cobalt（II） ions adopt hexa-coordinated distorted octahedral geometry. The electrochemical and fluorescence properties of the title complex are also discussed.展开更多
